odd, n>1, `p^n<255`

Comment(by SimonKing):
I have updated both patches, because I wanted to add one method:
`matrix_from_rows`. One could rely on the generic implementation, but in
some application I need this to be fast:
{{{
sage: MS = MatrixSpace(GF(5^3,'y'),3,2)
sage: A = MS(range(6))
sage: A
[0 1]
[2 3]
[4 0]
sage: A.matrix_from_rows([2,1])
[4 0]
[2 3]
sage: A.matrix_from_rows([1,1])
[2 3]
[2 3]
}}}
